Abstract

The invention relates to the technical field of printing rollers, in particular to a ceramic anilox roller and a preparing process thereof. The roller comprises a roller body, a nicochrome layer arranged on the outer surface of the roller body and a chromic oxide ceramic layer arranged on the outer surface of the nicochrome layer; reticulated mottles used for loading ink are arranged on the outersurface wall of the chromic oxide ceramic layer. According to the ceramic anilox roller, the nicochrome layer is arranged between the roller body and the chromic oxide ceramic layer, the chromic oxideceramic layer and the roller body are firmly combined, a corrosion agnet in ink can be effectively prevented from intruding into the roller body, the hardness is high, the roller is resistant to wear, corrosion and high temperature and has the beneficial effects of being long in service life, high in printing precision and capable of saving cost, and the ceramic anilox roller is high in compactness, uniform in coating thickness and ideal in smoothness and facilitates laser engraving.

Description

technical field [0001] The invention relates to the technical field of printing rollers, in particular to a ceramic anilox roller and a preparation process thereof. Background technique [0002] The anilox roller is a supporting part of the flexographic printing machine. The earliest anilox roller is an iron roller, and then the anilox is embossed on the surface of the roller. The production is relatively rough, and the wear is also great during use. It was difficult to guarantee the cost, which restricted the promotion of flexographic printing, which was mainly used in carton packaging at that time. [0003] With the development of the flexo printing industry, the anilox roller was later improved, and a layer of hard chrome was electroplated on the outer surface of the embossed roller to enhance the surface hardness of the anilox roller (usually at Rockwell HRC55-HRC60 , between Vickers HV600-750), to extend its service life, which is the prototype of the electrochrome-pla...
